Saya mencoba me-mount sftp
koneksi ke folder menggunakan sshfs
dengan perintah berikut yang melempar kesalahan.
~$ sshfs admin@example.com:/ testfo
remote host has disconnected
Kesalahan yang sama terjadi jika saya SSH ke dalam sistem dan ulangi perintah dengan localhost
. Perintah ini juga bekerja dengan komputer lain sehingga masalahnya ada di suatu tempat di server.
~$ cat /var/log/auth.log

The ~/.ssh
direktori dimiliki oleh admin karena saya melihat bahwa sebagai upaya debugging untuk masalah serupa.
Informasi tambahan untuk referensi di masa mendatang:
Masalahnya bukan dengan SSH itu sendiri, tetapi dengan SFTP. Ini dimanifestasikan oleh fakta bahwa koneksi SSH bekerja dengan benar tetapi SFTP selalu gagal. Mencoba hasil SFTP diReceived unexpected end-of-file from SFTP server
Masalahnya tidak terkait dengan string skrip login yang dihasilkan (misalnya ~/.bashrc
).
Masalahnya hadir dari semua pengguna (termasuk root).
Ini konfigurasi sshd saya ( /etc/ssh/sshd_config
):

paket diinstal. ( sudo apt-get install openssh-sftp-server

sftp
ke pengguna yang berbeda? 3) Bagaimana sshd_config
penampilan Anda di server? 4) Bagaimana ~/.bashrc
penampilan Anda ?
which sftp-server
. Subsistem seharusnya Subsystem sftp /usr/lib/openssh/sftp-server
. Apakah Anda sudah sftp-server
menginstal? apt-get install openssh-sftp-server
.
sftp
langsung ke sana? Apa isi~/.bashrc
atau file startup lainnya di direktori home server Anda?
